I am replacing batteries weekly.  I know I need to buy a power connector but, will it work on my older furnace?

Hi foodie, 

 

Thanks for reaching out to us, and I'm sorry to hear about the situation. I want to check if you are still in need of any help. If so, please answer the following:

 

  1. Are you located from North America or Europe?
  2. What type of Nest Thermostat do you have? 
  3. What is the make and model of your HVAC system? 
  4. How are the wires connected to your thermostat base? Could you send a photo of it? 
  5. When was it installed?
  6. Do you have more than one thermostat? If there's more than one thermostat:
    • Does the issue show up on the other thermostats too?
  7. When did the situation start?
  8. Is there a wiring report or message on your thermostat and/or app?
  9. Do you see a blinking LED light? If so, is it red or green?
    • If the LED is red: Have you tried charging the display through a different outlet using the adapter and cable?
    • If the LED is green: Have you tried manually restarting the thermostat?
  10. Has there been any recent work done on your thermostat(s) or heating system? If yes:
    • What was it?
    • How long was the power off for?
  11. Were there any power outages? If yes:
    • When was the latest power outage?
    • How long did it last?
    • Has the thermostat been off since then?
  12. Were there any modifications to the internet configuration (for example: added extenders)?
  13. What are the power readings in Settings > Technical Info > Power (For Nest Learning Thermostat and Nest Thermostat E) and Settings > Equipment > Power Info (For Nest Thermostat 2020).
  14. Is the thermostat display responsive when interacting with it?
  15. What troubleshooting steps have you done?

 

I'll look forward to your response. 

 

Best,

Zoe
